This invention relatesto agame ball catapult.

Antobjectof the'sinvention 'is to provide 'a game apparatus including aclub or ballsprojector.

A further object of. the invention-is to provide game apparatusincluding a club or ball projector having novel and simplifiedconstruction.

Afurtherobject of-the invention is lac-"provide game apparatus of theabove'mentionedclass which is durable; easy to operate, and practicaland inexpensive to manufacture.

Other objects and advantagesof. the invention will" be apparentduringthe course of 'the' following description.

In the accompanying drawings, forming a part of this application, and inwhich like numerals are employed to designate like parts throughout thesame,

Figure 1 is a side e evation of the club or ball projector, andillustrating the action of the same.

Figure 2 is a plan view of the club or projector.

Figure 3 is an enlarged fragmentary central longitudinal section throughthe club shank and sliding handle section mounted thereon.

Figure 4 is a transverse vertical section on line 5-5 of Figure 4.

Figure 5 is an enlarged fragmentary section through the movable head orhammer of the club.

In the drawings, where for the purpose of illustration. is shown apreferred embodiment of our invention, the numeral !5 designates a clubor ball projector as a whole, and this club is preferab y formed of asingle sect on of suitable standard metal tubing of a light gage, andbent or formed into the desired shape. The club l5 comprises a projectsupwardly from the ground and is inclined rearwardly when the club is inuse, Figure 1. The top end of shank it carries a relatively stationaryhandle section IV, as shown.

At its lower end It, shank is is bent downwardly and laterally out ardlyto form a substant ally vertical depending leg !9, bent at i s bottomend to form a circularly curved side 20 of a horizontal circular ring orground-engaging foot 2!. The ring 2! includes an oppositecircularly-curved side 22, having a free end 23 spaced slightlylaterally from shank l6, as viewed in Figure 3. Side 22 is carried bythe bottom end of one straight upwardly-inclined side 24 of aforwardly-projecting upwardly-inclined track straight elongated shank16, which 311';

' shank. Inzitsfiiree position, thestrap 28 is: straight:

andnslig htly. inclinedxdownwardly-itowarda itsfor:- ward end, which isdisposed slightly forwardly of ring2 I. Rigidlymounted uponthe top sideof strap 28, at its forward end is a propelling block or hammer 29,having a circularly-curved concave forward face 30. Face 30 islongitudinally curved, with respect to strap 28. The block 29 is securedto strap 28 by means of screws 3|, or the like. The block is preferablyof the same width as strap 23. Near its forward tip, strap 28 isprovided with an eye-screw 32, which is anchored in the block 29, asshown. A flexible element or wire 33 is connected at its lower end toeyescrew 32, as shown, and at its top end to an eyescrew 34, anchored inthe lower end of a slidable handle section 35, mounted upon shank it.The handle section 35 is generally cylindrical, and free to slidelongitudinally on shank it above end 29'.

In making a shot, the slidable handle section 35 is pulled toward theupper end of club shank l5. flexing the resilient strap 28. The ball 36is placed at the bottom end of track 25, and careful aim is taken. Thehandle section 35 is then released and block or hammer 29 will propelball 36 up the track 25 and through the air toward a target. Skill inthe use of the club, and the extent of pull on handle section $5 areacquired by practice. The club is light and easy to manipulate.

It is to be understood that the form of the invention, herewith shownand described, is to be taken as a preferred example of the same, andthat various changes in the shape, size and arrangement of parts may beresorted to, without departing from the spirit of the invention, or thescope of the subjoined claims.

Having thus described the invention, we claim:

1. A game ball catapult, comprising an elongated straight inclinedshank, a substantially horizontal loop secured to the lower end of theshank for engagement with the ground and adapted to receive the balltherein, an upwardly inclined straight track secured to the loopdiametrically opposite the shank, the shank and track divergingupwardly, a leaf spring secured to the shank and having its free endextending above the loop when the leaf spring is in the untensionedposition, and a flexible element connected with the leaf spring near itsfree end and adapted to be pulled longitudinally of the shank for bowingthe leaf spring so that it engages behind the ball and being releasableso that the leaf spring can propel the ball up the track.

2. A game ball catapult, comprising an elongated straight inclinedshank, a substantially horizontal base secured to the lower end of theshank for engaging the ground and adapted to receive the ball, aninclined straight track secured to the base at its side opposite theshank, the shank and track diverging upwardly, a normally substantiallystraight leaf spring secured to the shank near one end and extendingabove and across the base when in the normal untensioned position, anelement mounted upon the shank and adapted to slide longitudinallythereon, and a flexible element connecting the element and leaf springand serving to draw the free end of the leaf spring downwardly near thebase and behind the ball when the element is pulled toward the top ofthe handle, the leaf spring propelling the ball up the track when theelement is released;

3. A game ball catapult, comprising a unitary continuous rod includingan elongated straight inclined shank portion, the rod being bent at thebottom end of the shank portion to form a substantially horizontalarcuate section, the rod being bent at the end of the arcuate sectionremote from the shank portion to form a straight inclined invertedU-shaped track portion disposed diametrically opposite the shankportion, the shank portion and track portion diverging upwardly, the rodbeing further bent at the free end of the track portion to form acompanion substantially horizontal ar'cuate section disposed laterallyopposite the firstnamed arcuate section and forming therewith a groundengaging base, a leaf spring secured to the shank portion and extendinggenerally longitudinally of the shank portion and over the base, asleeve mounted upon the shank portion for longitudinal sliding movement,and a flexible element connected with the leaf spring near its free endand with the sleeve.
